To all whom it may concern.'

,Be it known that I, JOHN F. OCoNNoR, a citizen of the United States,residing at Chicago, inthe county of Cook and State oflllinois, haveinvented a certain new and useful .improvement in Side Bearings forRailway- Cars, of which the following is a full, clear, concise, andexact description. reference be to the accompanying drawings, forming apart of this specification.

My invention relates to improvements in side bearings for railway cars.

One of the objects-of my invention is tok provide a simple and efiicientside bearing.

is to provide a gravity centering side bearing of few parts. Furtherobjects will appear from lthe description ofl the invention hereinafterfollowing.

in the drawings forming a part of this specification, Figure l is 'across section of the bolsters of a railroad car'showing my imroved sidebearing mounted therebetween. ig. 2 is a horizontal sectional view takenonline 2`2 of Fig. 1. `And Fig. 3 is a vertical section part in endview, the section line being shown at 3 3 in Fig. 1.

Referring to the drawings, the numeral l0 indicates' a body bolster'of arailroad car, only the lower portion thereof being shown, and 11 thetruck bolster, only the upper portion being shown. rlhe sidebearingconsists ofv three'V parts*the base member 12, the roller oranti-friction element 13, and the bearing plate let. The base member isof a general hollowrectangular shape openy at top and bottom andprovided with the lugs l5 by means of which it is'secured to the.truck'- bolster 11 by suitable means-'21s, for instance, the rivets16-16. The end walls 17%17 of the base member are each providedA with aslot 18 for the discharge of dirt and dust. One of the end walls-as, forinstance, that shown at the right-'hand in Fig. 1 of a slot 19 for theinsertion and withdrawal of the bearing plate 14 in the mannerhereinafter described. rihe bottom of the base member is partiallyclosed by the lower plates 119-119 there being provided between them thevertical opening 2O for the insertion of the roller within the basemember in the manner hereinafter described. p The roller oranti-friction element consists of a portion of general cylindrical shapereferenced 21, each side of which is Specification of Letters Patent.

provided preferably,v at its center with a.

groove 22. At either end and depending over the edges of the bearingplate liis a counter balance 23, preferably an integral part of themember 2l, and at the ends thereof are' the projecting members 24, eachlof hsaid members being preferably pentagonal in shape, serving ascentering guides for the anti-friction members as they are received inthe recesses 25 in each side Wall 26 of the base member, theconformation of the said ymembers being such that in all positions ofthe anti-friction member in its longitudinal movement within the basemember the said 1nembers'24'substantially span the recesses The recesses22 in the roller permit a narrower opening 2O than would be had were itnecessary to inserty the roller through the bottom portion of the basemember in assembling without the said recesses 22 therein. The sidewalls 26 of the base member are provided along their upper edge andforming the upper end of the recesses 25 with the ianges 27, whichprevent the upof the anti-friction ele` ment from the base member.

ln assembling the parts, the anti-friction member is passed through theopening 20 in the bottom of the base member until itis in its operativeposition. The said opening 20 is mostrcstricted between the bottomportions 119 of thebase member, and, as will be observed in Fig. 2 ofthe drawings, at either side of said bottom portions the base member isopen to permit the reception and movement therein of the counterbalances 23 hereinafter described. The'grooves 22, as hereinbeforeVmentioned,

permit the passageV of thev roller through theopening 20, which y l isof suitable width therefor. When the roller is in its position withinthe base memer, the bearing plate 14 is inserted through the opening 19until it rests upon the bottom portions 119 of the base member, as mostclearly shown in Fig. 1 ofthe drawings, and when in its position issecured therein Vby suitable means-as, for instance, the cotter key 2S.The base member is then secured in its position upona car bolster. lndisassembling the parts, the reverse of this operation is followed. Onmovement of the anti-friction element, whichy will occur on engagementof Vthe upper bolster 10 against the anti-friction element, the samerolls upon the bearing plate 14, and if the
